Annual ryegrasses are a one year proposition which establish rapidly and provide excellent quality autumn, winter and early spring growth.
The forage quality drops in late spring with the onset of seed head emergence, and plants are usually dead by summer.
Some annual cultivars are bred to provide quick winter feed, flower early and die and are typically suited to winter rainfall and areas with hot, dry summers.
Whereas other cultivars such as Winter Star® II, can be just as quick but continue to provide late season quality feed into summer if conditions are favourable.
Annual ryegrasses are a good option for over-sowing and improving existing pastures.
